We report a measurement of the strong coupling constant, alpha_s
(M_Z), extracted from inclusive jet production in p anti-p collisions at s**(1/2)
= 1800 GeV. The QCD prediction for the evolution of alpha_s with jet
transverse energy E(t) is tested over the range 40 < E(t) < 450 GeV using E(t)
for the renormalization scale. The data show good agreement with QCD in the
region below 250 GeV. In the text we discuss the data-theory comparison in
the region from 250 to 450 GeV. The value of alpha_s at the mass of the Z0
boson averaged over the range 40 < E(t) < 250 GeV is found to be alpha_s(M_Z)
= 0.1178 +/- 0.0001(stat)+0.0081_-0.0095(exp. syst). The associated
theoretical uncertainties are mainly due to the choice of renormalization
scale (+6%_-4%) and input parton distribution functions (5%).
